– Push the nail strip forwards in the magazine until the last
nail is positioned in front of the magazine spring (17).
Note: A lock function of the magazine slider prevents the
power tool from being started with an empty magazine. The
discharge lock-off cannot be pressed down and blank firing
is thus prevented.
– Press the pretensioned nail pusher (14) against the
magazine slider (13) and, at the same time, pull the
magazine slider completely to the end of the
magazine (12).
Note: The magazine slider must slide back with only low
force (finger-pressure). A tight-running magazine slider
causes the nails to be driven in at an incorrect angle.
– With the nail pusher (13) pressed, carefully guide the
magazine slider (14) forwards until the nail pusher is over
the last nail, thus pushing the nail strip in the magazine
completely to the front.
Note: Do not let the magazine slider snap back without guid-
ing it. This could damage the magazine slider and there is a
risk of getting your fingers caught.
Operation
Actuation systems
Single actuation with safety run
With this actuation system, the discharge lock-off (2) must
first be firmly pressed against the workpiece. A fastener is
not discharged until the trigger (5) is pulled.
Afterwards, further discharging procedures can only be ac-
tuated when the trigger and the discharge lock-off have been
set back to the starting position.
Contact actuation with automatic return
(GNH 18V-64 M)
With this actuation system, the trigger (5) must be pulled
first and held in this position. Afterwards, the discharge
lock-off must be firmly pressed against the workpiece in or-
der to discharge the fastener. (5)Further discharging pro-
cedures can be actuated by repositioning it elsewhere, while
the trigger is pushed.
In contact actuation mode, a nail can also be driven in with
single actuation.
